## Summary

### Public methods
`static CompactNotation` | `compactLong()` Print the number using long-form compact notation.
`static CompactNotation` | `compactShort()` Print the number using short-form compact notation.
`static ScientificNotation` | `engineering()` Print the number using engineering notation, a variant of scientific notation in which the exponent must be divisible by 3.
`static ScientificNotation` | `scientific()` Print the number using scientific notation (also known as scientific form, standard index form, or standard form in the UK).
`static SimpleNotation` | `simple()` Print the number using simple notation without any scaling by powers of ten.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public methods

### compactLong

    public static CompactNotation compactLong ()

Print the number using long-form compact notation. For more information on compact notation, see `compactShort()`.

In long form, the powers of ten are spelled out fully. Example outputs in en-US when printing 8.765E7 through 8.765E0:

     88 million
     8.8 million
     876 thousand
     88 thousand
     8.8 thousand
     876
     88
     8.8

Returns
`CompactNotation` | A CompactNotation for passing to the NumberFormatter notation() setter.

- `NumberFormatter`

### compactShort

    public static CompactNotation compactShort ()

Print the number using short-form compact notation.

Compact notation, defined in Unicode Technical Standard #35 Part 3 Section 2.4.1, prints numbers with localized prefixes or suffixes corresponding to different powers of ten. Compact notation is similar to engineering notation in how it scales numbers.

Compact notation is ideal for displaying large numbers (over ~1000) to humans while at the same time minimizing screen real estate.

In short form, the powers of ten are abbreviated. In en-US, the abbreviations are "K" for thousands, "M" for millions, "B" for billions, and "T" for trillions. Example outputs in en-US when printing 8.765E7 through 8.765E0:

     88M
     8.8M
     876K
     88K
     8.8K
     876
     88
     8.8

When compact notation is specified without an explicit rounding strategy, numbers are rounded off to the closest integer after scaling the number by the corresponding power of 10, but with a digit shown after the decimal separator if there is only one digit before the decimal separator. The default compact notation rounding strategy is equivalent to:

     Rounder.integer().withMinDigits(2)

Returns
`CompactNotation` | A CompactNotation for passing to the NumberFormatter notation() setter.

- `NumberFormatter`

### engineering

    public static ScientificNotation engineering ()

Print the number using engineering notation, a variant of scientific notation in which the exponent must be divisible by 3.

Example outputs in en-US when printing 8.765E4 through 8.765E-3:

     87.65E3
     8.765E3
     876.5E0
     87.65E0
     8.765E0
     876.5E-3
     87.65E-3
     8.765E-3
     0E0

Returns
`ScientificNotation` | A ScientificNotation for chaining or passing to the NumberFormatter notation() setter.

See also:

- `NumberFormatter`

### scientific

    public static ScientificNotation scientific ()

Print the number using scientific notation (also known as scientific form, standard index form, or standard form in the UK). The format for scientific notation varies by locale; for example, many Western locales display the number in the form "#E0", where the number is displayed with one digit before the decimal separator, zero or more digits after the decimal separator, and the corresponding power of 10 displayed after the "E".

Example outputs in en-US when printing 8.765E4 through 8.765E-3:

     8.765E4
     8.765E3
     8.765E2
     8.765E1
     8.765E0
     8.765E-1
     8.765E-2
     8.765E-3
     0E0

Returns
`ScientificNotation` | A ScientificNotation for chaining or passing to the NumberFormatter notation() setter.

- `NumberFormatter`

### simple

    public static SimpleNotation simple ()

Print the number using simple notation without any scaling by powers of ten. This is the default behavior.

Since this is the default behavior, this method needs to be called only when it is necessary to override a previous setting.

Example outputs in en-US when printing 8.765E7 through 8.765E0:

     87,650,000
     8,765,000
     876,500
     87,650
     8,765
     876.5
     87.65
     8.765

Returns
`SimpleNotation` | A SimpleNotation for passing to the NumberFormatter notation() setter.
